Pro-Dragon/Parallax-japanese-theme ? reverse-engineered prompt

Build me a stylish Japanese inspired parallax website landing page that feels calm, modern, and a little cinematic.

I want a single page experience with smooth scrolling, layered background sections, and a strong visual focus on Japanese aesthetics like cherry blossoms, night city lights, temples, waves, or mountain scenery. It should look polished on desktop and mobile, with nice typography, clear sections, and subtle motion that makes the page feel alive without being distracting.

Use the existing HTML, CSS, and JavaScript files to make the page work well as a complete theme. Add any small interactive touches that fit, like scroll based effects, navigation that feels smooth, or elements that move at different speeds as you scroll. Keep the code clean and easy to tweak later.

If you need current browser guidance or best practices, look them up online. Also make sure the page is ready to open as a simple static site and looks good right away.
